Ilyushin Il-102

In 1967, the Soviet Air Forces drew up a specification for a jet-powered shturmovik or armoured ground attack aircraft. While Sukhoi designed an all-new single seat aircraft, the Su-25, Ilyushin proposed a modified version of their Il-40 of 1953 under the designation Il-42, which, unlike the Sukhoi, was a two-seat aircraft with a remotely-controlled rear gun turret. The design was rejected by the Soviet Air Forces, but Ilyushin decided to continue in-house development regardless, renaming the programme Il-102.^[1]

The Il-102 first prototype flew on 25 September 1982, with a second airframe built for static tests, and carried out 250 test flights until it was grounded in 1984 when the engine life expired.^[2]

 

The Il-102 was a low-winged monoplane with moderately swept (30 degrees) wings, powered by two Klimov RD-33I turbofans (non-afterburning versions of the engines that power the Mikoyan MiG-29 fighter). It was highly unusual for its time in having a rear gun turret, something not seen in ground-attack aircraft since the World War II Il-2 Shturmovik and Il-10, the Il-102's spiritual ancestors, controlled remotely by a gunner sitting in a cockpit above the trailing edge of the wing. The crew cockpits, engines and fuel tanks were armoured to protect against ground fire.^{[citation needed]}

Although development was abandoned in 1984, the prototype Il-102 was publicly unveiled at the 1992 Mosaeroshow air show at Zhukovsky, being claimed to be available for export.^[3]

 

As of 2005, the prototype No. 10201 was placed on display at the Gromov Flight Research Institute.^{[citation needed]}
